Subject: 20011115: NEXRAD reflectivity mosaic availability


As a service to the community, 2 NEXRAD reflectivity mosaic products
are available on the FNEXRAD data feed. One is a 6km national composite.
The other is a 1km regional floater. These are the products used to
create the example images shown at:
http://motherlode.ucar.edu/unidata/images/nids/gdradr.html

Millersville University has accepted the job for selecting the floater region
which is being created for the IDD.

The radar composites on FNEXRAD are distributed in standard GRIB format
so that users can access the data locally using a variety of data
display tools.

The composites are created using the GEMPAK program GDRADR which is described
in more detail at:
http://www.unidata.ucar.edu/packages/gempak/examples/gdradr/
Examples of other uses of the products are also shown on the above web page.

Any site receiving NEXRAD data can create their own mosaics locally
using GDRADR. The products on the FNEXRAD feed provide an alternative
for sites that do not want to receive all the NEXRAD radar data,
or may only want to create their own local region composites.

LDM pqact.conf examples, and further information on decoding and displaying
the products can be found here:
